SALT OR PEPPER DREDGE.

SPECIFICATION forming part of Letters Patent No.352,3'76, dated November 9, 1886.

Application filed July 12, 1886. Serial No. 201,731. (No model.)

To all whom it may concern:

Be it known that I, ROBERT WALLACE, of Wallingford, in the county of New Haven and State of Connecticut, have invented new Imp'rovements in Salt or Pepper Dredges; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1, a side view, half in vertical section; Fig. 2, the cap detached.

This invention relates to an improvement in salt or pepper dredges for table use, having special reference to the class of such articles in which the dredge is made from glass or similar non-metallic material and provided with a metal cap.

In the usual construction of this class of dredge a metal collar is constructed with a screw-thread, and is secured to the bottle by plaster-of-paris or other cement, and the perforated cap, correspondingly screw-threaded, is removably secured to the collar. Notwithstanding great care may be taken in securing the collar to the bottle, they frequently become disconnected, to the great annoyance and inconvenience of the user.

The object of my invention is to dispense with the collarin this class of dredge.

A represents the bottle, which is made from glass or other non-metallic material. It is constructed with an opening, a, at the upper or neck end, and upon the inside is an annular shoulder, 1), below the upper edge of the neck. The shape of the body or bottle may be of any desirable pattern. The opening in the neck is preferably made cylindrical.

B is the cap, which may be the usual form perforated. Below the perforated portion is an annular rib, d, of larger diameter than the opening in the neck. Below the rib d a concentric flange, 6, extends downward, in length corresponding to the distance between the shoulder 12 and the outer end of the neck. This flange terminates in a slight outward projection, f. The flange is divided vertically by several slits, 9, so as to form a series'of springs (more or less in number) projecting downward from the rib d, and so that the extent of the flange maybe considerably contracted. The cap is set into the bottle by introducing the flange-springs into the opening in the neck and forcing them down until the rib d rests upon the top of the neck, at which time the projection fat the lower end of the springs is free to fly outward and beneath the shoulder b upon the inside of the bottle, as seen in Fig. 1. The cap therefore rests upon the rib d, and is held there by the frictional contact of the springs upon the under side of the neck and the lateral projections f from the springs; but these projections are rounded, or of such a nature as to permit them to pass up from the shoulder when the cap is pulled upon, so that the springs will be contracted in such pulling upon the cap, so as to permit the removal of the cap. By this construction not only is permanent attachment of the cap to the bottle assured, but the trouble and inconvenience in the use of the collar, as well as the expense of the collar, is avoided, for the expense of making the cap with the springs is no greater than to construct the cap with the usual screw-thread.

I am aware that stoppers and covers have been applied to vessels of a bottle-like character, the stoppers adapted to engage correspond ing shoulders within the bottle by springextensions from the stopper, such as found in United States Patents No. 343,207 and No. 337,003, and therefore do not claim, broadly, such a device; but I am not aware that a thin metal perforated cap having an annular rib upon its outside to rest upon the top of the bottle, the sides of the cap extended below the rib in the form of a concentric flange, the said flange having an annular rib around its lower edge upon the outside,',.and the flange slit vertically to form springs, the neck of the bottle having an internal annular shoulder with which the said rib on the flange may engage, such construction of cap constituting the essential feature of my invention.

I claim The combination of the bottle A, open at the neck, and with an annular recess, b, within adapted to engage the shoulder in the neck of the neck, a thin metal perforated cap, B, conthe bottle while the annular i'ib d rests on the structed with an annular rib, a, below the perforated portion of the cap, and the sides of the top of the bottle, substantially as described. cap extended below the said rib d to form a 5 thin concentric flange having an annular rib, Witnesses:

f, around its lower edge, andthe said flange W. J. LEAVENWORTH, having vertical slits g, the said annular rib f GEO. T. JONES.
